n. An instrument for producing and observing spectra.

n. An optical instrument for forming and examining spectra (as that of solar light, or those produced by flames in which different substances are volatilized), so as to determine, from the position of the spectral lines, the composition of the substance.

n. An instrument used to produce a spectrum of the light (or, more generally, the radiation) from any source by the passage of the rays through a prism or their reflection from a grating, and for the study of the spectrum so formed.

To use the spectroscope; study by means of observations with the spectroscope.

n. an optical instrument for spectrographic analysis

"You will find it very interesting to make the first of Newton's experiments yourself, and some day perhaps you will hear what wonderful things about the sun and the stars are being learnt in our own time by means of the spectroscope, which is an instrument having a fine slit through which the ray is passed before it is allowed to fall upon the prism."
